Home Forums Hunting & Shooting Handguns Bonded vs Non-Bonded 9mm, 40, 45 ?

I got a mid-size plastic ammo box with their logo on it, some CCI Mini Mags, a box of .357 Hydra-Shoks, and something else. It was all stuff that was very relative to the types of things I order. Not worth a whole bunch, but also very appreciated since they don't have to do that.

Bottom Line: Don't join Prime for the gift. Join if you want to place 15 ammo orders per year, get an 8% discount and free shipping.

Good info folks.

Agree with you JWP, penetration is first, have to reach the target.......

My free gift was a NEW Metal ammo box, with a keychain, decals and a box of 9 mm ammo inside. As stated, I believe they use your order history to select something for you. Frankly, being able to order at will with free shipping and the 8% discount more than makes up for the cost. Hell, split the cost with a relative or friend and it makes it even more of a bargain!

For instance, I just ordered a 2 brick batch of Armscor .22LR 36 gr hp to try out an as it was free shipping, the cost was only $.03 a round....my guns appear to like it and at that price, it's inexpensive plinking hunting ammo. I wouldn't have wanted to order a full case to get free shipping, not knowing how it performed.

Meh, I see a trend. Guys are running +p, +p+. Why not just step up to the 357 Sig.

+P 9mm ammo penetrates deeper than +P+ because the bullets over expand at the higher speed of the +P+. The 357 bullets are designed for the added velocity. The 357 Sig looses 2 rounds of magazine capacity to the 9mm, the same as the 40 S&W does.

THIS

The added velocity of +P or the .357 Sig is more about barrier penetration.

The 357 Sig bullets are tougher than the 9mm bullets and not suffer from over expansion

Good info folks.

So GunGeek and JWP, which round do you prefer?

I carried a 1911 45 ACP in +P and 45 Super for decades but have switched to 9mm for more capacity

I've been carrying 2 different loads 125 grain +P Bonded in my P365 and Hornady 136 grain +P Critical Duty in P320 X Carry

I goi g to get a P320 in 35u Sig and give it a whirl with the Underwood 125 JHP at an advertised 1475 FPS. I've watched a couple of videos on YouTube that they choreographed them at 1500+. That will leabd a mark that won't buff out.

I think it will ! Lol

Lots of good info for the most part. Curious: Any opinions regarding Win Bonded .45 Auto PDX1 230gr JHP ammo? Thanks.

For me the difference is about shooting faster accurately. If you're considering a cartridge in terms of a single shot that's different, I've got a 460 S&W for that. For a carry gun though, in comparable guns (Glocks in my case) and loads I can shoot +P+ 9mm faster with the same level of accuracy compared to 357 Sig. And in my case, that's even with a slight advantage to the 357 since mine is in the larger G22 frame with an extended G35 barrel, comparing to 9mm in a G19. Both have RMR red dot sights and both are capable of excellent accuracy.

With that said, I wouldn't look down on anyone carrying the 357 Sig. It's a great cartridge with some definite advantages in trajectory and power. I prefer the 90gr Lehigh Defender in either cartridge; either Underwood or equivalent handloads. That does ~1525 fps in my G19 (9mm +P+) while being easier to shoot than their +P+ 124gr Gold Dot load, and ~1750 fps in the 357 Sig although I've found it easy to exceed that with handloads in the 357.

As a side note - I tested both extensively in barriers, test media, and meat/bone, and much prefer the 90gr over the 65gr version of the same. The 65gr was FAST (over 1850 fps in my G19) but did not penetrate nearly as well in soft media or meat, being approximately similar in penetration to the 115gr Barnes which IMO doesn't penetrate all that well. It was good for punching through hard plate though with it's high velocity. IMO the 90gr seems a better compromise of penetration vs speed, trajectory, and follow up shot speed compared to heavier bullets.
